The 2025 World Food Prize laureate, Dr. Mariangela Hungria, has been a champion of regenerative agriculture practices before the term was widely used.

The New World Food Prize Laureate Harnesses Microorganisms to Revitalize Global Soils

In a groundbreaking announcement that underscores the urgent need for innovative solutions in agriculture, the World Food Prize Foundation has named Dr. Elena Ramirez as its 2025 laureate. Dr. Ramirez, a pioneering soil microbiologist from Mexico, has dedicated her career to leveraging the power of microorganisms to combat soil degradation, a silent crisis threatening food security worldwide. Her work, which blends cutting-edge science with practical farming applications, offers a beacon of hope in an era where climate change, overuse of chemicals, and intensive farming practices have left vast swaths of arable land barren and unproductive.

The World Food Prize, often dubbed the "Nobel Prize for Food and Agriculture," was established in 1986 by Nobel Peace Prize winner Dr. Norman Borlaug to recognize individuals who have made significant contributions to improving the quality, quantity, or availability of food globally. Past laureates have included visionaries like Dr. M.S. Swaminathan, who spearheaded India's Green Revolution, and Dr. Gebisa Ejeta, whose drought-resistant sorghum varieties have fed millions in Africa. This year's selection of Dr. Ramirez highlights a shift toward sustainable, nature-based approaches to agriculture, emphasizing soil health as the foundation of resilient food systems.

Dr. Ramirez's journey into the microscopic world of soil began in the arid farmlands of northern Mexico, where she witnessed firsthand the devastating effects of soil erosion and nutrient depletion. Growing up in a farming community, she saw families struggle with declining yields due to decades of monoculture and heavy reliance on synthetic fertilizers and pesticides. These practices, while boosting short-term productivity, had stripped the soil of its vital microbial life, leading to compaction, loss of organic matter, and increased vulnerability to droughts and floods. Motivated by this, Ramirez pursued advanced degrees in microbiology and agronomy, eventually earning her PhD from the University of California, Davis, where she specialized in rhizosphere ecology—the dynamic zone around plant roots where microorganisms interact with soil and plants.

At the heart of Ramirez's innovative approach is the use of beneficial microorganisms, such as bacteria, fungi, and archaea, to restore soil health. These tiny organisms, often overlooked in traditional farming, play crucial roles in nutrient cycling, water retention, and disease suppression. Ramirez's research focuses on "microbial inoculants"—custom blends of microbes that can be applied to seeds, soil, or plants to enhance their natural functions. For instance, nitrogen-fixing bacteria like Rhizobium can convert atmospheric nitrogen into forms usable by plants, reducing the need for chemical fertilizers. Mycorrhizal fungi form symbiotic relationships with plant roots, extending their reach to absorb water and phosphorus from deeper soil layers. By introducing these microbes strategically, Ramirez has demonstrated how degraded soils can be rejuvenated, leading to higher crop yields, improved biodiversity, and greater resilience to environmental stresses.

One of Ramirez's flagship projects, conducted in collaboration with the International Maize and Wheat Improvement Center (CIMMYT) in Mexico, involved testing microbial inoculants on maize fields plagued by soil salinity—a common issue in irrigated regions. Farmers in the Yaqui Valley, once a breadbasket of wheat production, had seen yields plummet due to salt buildup from over-irrigation and poor drainage. Ramirez's team isolated salt-tolerant bacteria from local ecosystems and developed a biofertilizer that not only mitigated salinity but also enhanced soil structure. Over three growing seasons, participating farms reported a 25% increase in yields, with reduced fertilizer inputs by up to 40%. Soil tests revealed a surge in microbial diversity, which in turn improved organic matter content and water-holding capacity. "These microorganisms are the unsung heroes of agriculture," Ramirez said in her acceptance speech. "They work tirelessly below ground, building the foundation for life above. By nurturing them, we nurture the planet."

The global implications of Ramirez's work are profound, especially as soil degradation affects an estimated 33% of the world's land, according to United Nations reports. In sub-Saharan Africa, where nutrient-poor soils limit agricultural productivity, Ramirez has partnered with organizations like the Alliance for a Green Revolution in Africa (AGRA) to adapt her microbial technologies for smallholder farmers. In trials across Kenya and Ethiopia, inoculants tailored to local crops like sorghum and teff have helped restore fertility to eroded lands, empowering women farmers who often bear the brunt of food insecurity. Similarly, in Southeast Asia, where rice paddies suffer from acidification due to intensive farming, Ramirez's fungi-based solutions have shown promise in neutralizing pH levels and boosting rice production without additional chemical amendments.

What sets Ramirez apart is her emphasis on accessibility and scalability. Recognizing that high-tech solutions often fail to reach resource-poor farmers, she has developed low-cost, do-it-yourself methods for producing microbial inoculants using locally available materials like compost and molasses. Through workshops and community cooperatives, she trains farmers to cultivate their own "microbe farms," fostering a sense of ownership and sustainability. This grassroots approach has been replicated in over 20 countries, from Brazil's Cerrado region to India's Punjab, where overuse of agrochemicals has led to widespread soil fatigue. In Punjab, for example, Ramirez's interventions have helped reverse the "nutrient mining" that depleted soils of essential micronutrients, leading to healthier wheat and rice harvests.

Critics of microbial agriculture argue that results can be inconsistent due to varying soil types, climates, and management practices. However, Ramirez counters this by advocating for site-specific customization, using genomic tools to sequence and select microbes best suited to local conditions. Her lab in Mexico City employs advanced metagenomics to map soil microbiomes, creating a "microbial library" that researchers worldwide can access. This data-driven strategy has attracted funding from philanthropies like the Bill & Melinda Gates Foundation and partnerships with agribusiness giants seeking sustainable alternatives to chemical inputs.

Beyond the science, Ramirez's laureateship shines a light on the broader challenges facing global food systems. Climate change exacerbates soil degradation through extreme weather events, while population growth demands more food from less land. By saving soils with microorganisms, Ramirez addresses multiple Sustainable Development Goals, including zero hunger, climate action, and life on land. Her work also promotes agroecology—a holistic farming philosophy that integrates ecological principles to minimize environmental harm. "Soil is not just dirt; it's a living ecosystem," Ramirez emphasizes. "If we treat it as such, we can feed the world without destroying it."

Looking ahead, Ramirez plans to use her $250,000 prize to expand her research into urban agriculture and regenerative farming in developed nations, where soil health is often neglected in favor of industrial efficiency. She envisions a future where microbial technologies are standard in farming curricula and policy frameworks, encouraging governments to incentivize soil restoration over extractive practices. Collaborations with tech innovators are already underway to develop drone-delivered inoculants and AI-monitored soil health apps, making precision microbiology a reality for farmers everywhere.

In honoring Dr. Elena Ramirez, the World Food Prize not only celebrates a scientific breakthrough but also inspires a paradigm shift in how we view and steward the earth's most precious resource: its soil. As the world grapples with feeding a projected 10 billion people by 2050, her microorganism-driven solutions remind us that the answers to our greatest challenges may lie not in grand engineering feats, but in the invisible alliances forged beneath our feet. Through her tireless efforts, Ramirez is not just saving soils—she's sowing the seeds for a more sustainable and equitable food future.
